I have had this issue for sometime and want to see if Intova has had other feedback from divers about this issue, and if anyone else has this issue with their Nova series torches. I forget the exact model of my torch but it is one of the older Intova Novas
I have had particles become trapped beneath the glass and unable to remove them with continuous washing, soaking ect. I have also noticed the glass to become "fogged" and no it is not from the change in temp it is like this all the time. I do not see any easy visible way of removing the glass it appears that you would need a specific tool to fit in the slots around the frame which I do not have and have not found anything in my local hardware stores that would fit to remove the glass.
